The first thing my husband Ronny did was cut 3 pieces of 2 x 4’s each into 24″ lengths. These are going to help the wall cushion have a slight angle for back support.
Next Ronny cut the plywood to the size of our desired wall cushion, 79″ L x 20″ H using our table saw.
He then drilled on the three 2″ x 4″ pieces to the bottom side of the plywood as shown in the picture below.
